Nine Inch Nails last night confirmed 800,000 online sales of the band's latest Ghosts I-IV album in the first week, generating $1.6 million in revenue.

The band made the album available for download earlier this month, and last night confirmed 800,000 sales in the first week, generating $1.6 million in revenue.

The sales included free and paid downloads as well as orders made online for the slew of physical products the band has also made available, including boxed sets and vinyl. A special edition CD is set to ship in April in the UK.

Fans are being offered the first nine tracks taken from the album as DRM-free MP3 files at no charge. If they enjoy these they can also purchase all 36 album tracks in the DRM-free MP3 format for just $5.

Reznor advocates the potential for artist-focused digital distribution using the internet.
